A vast academic literature illustrates that voter turnout is affected by the institutional design of elections (e.g., compulsory voting, electoral system, postal or Sunday voting). In this article, we exploit a simple Downsian theoretical framework to argue that the institutional framework of public good provision – and, in particular, the distribution of political and administrative competences across government levels – likewise affects voters’ turnout decisions by influencing the expected net benefit of voting. Empirically, we exploit the institutional variation across German municipalities to test this proposition, and find supportive evidence.
